      <title>CVE-2026-92002 — MISP: Authentication failure logging suppressed during Redis unavailability</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-92002</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; MISP&lt;/p&gt;
&lt;p&gt;Affected versions of MISP use Redis to throttle repeated authentication-failure log entries. The intent is to avoid excessive duplicate logs while still recording failed authentication activity.&lt;/p&gt;
&lt;p&gt;However, User-&amp;gt;setupRedis() returns false when Redis cannot be reached. The vulnerable _shouldLog() logic only returned true when a Redis instance existed and no throttle key was present. Therefore, when Redis was unavailable, the function did not allow the log write at all, effectively silencing authentication-failure logging for the duration of the outage.&lt;/p&gt;
&lt;p&gt;Version affected: ≤2.5.45&lt;/p&gt;</description>
